Stepper motor is an open-loop control motor that converts electrical pulse signals into angular displacement or linear displacement. It is the main executive element of modern digital program control systems. It is widely used. Under non-overload conditions, the speed and stop position of the motor are only Depends on the frequency and pulse number of the pulse signal, and is not affected by the load change. When the stepper driver receives the pulse signal, the stepper motor rotates in a given direction by a fixed angle, which is called "step angle". That is, the rotation of the stepping motor, which works step by step from a fixed angle, and controls the angular displacement by controlling the number of pulses to achieve precise positioning. At the same time, by controlling the pulse frequency to control the motor speed and acceleration to achieve speed regulation the goal of.
1. Stepper motor driver response test
The response test is mainly to apply different loads to the motor through the motor test bench, pay attention to whether the motor drive can quickly adjust the working state of the motor according to the algorithm when the load changes, and evaluate the response performance of the drive. This test method can be said to be one of the most commonly used methods to determine whether the driver is aging.
2. Perform driver performance test
The drive performance test mainly focuses on test items such as drive efficiency, harmonic analysis, three-phase unbalance analysis, and interference analysis. If these data are qualified, it means that they have not aged.
These performances are also important indicators for judging the performance of the motor when the motor assembly line produces motor equipment.
